Okey .. i have this box:
Motherboard P5Q3
CPU: Q9550
Memory: A Data DDR3 2 x 1 GB 1600 Mhz ...


i installed slackware 12.1, 12 and 11
all 3 crash after some hours of uptime ... after manually restarting the box from the button everything is good for another 4 .. 5 .. 6 hours

i only have bind, sendmail, apache & sql ( xampp ) running on the machine.


Anybody have any ideeas ?
I heard that the motherboard has a chipset that is not supported ..
What chipsets are supported for slack 12.1 that go with my Q9550 CPU and DDR3 memories ?

I verifyed the Memory with memtest and everything is good.

Can you look through the system logs and see if there is anything suspicious at the time of the crash ? Look in '/var/log' for syslog and messages.

Absolutly nothing ... just crashes .. i've looked through all logs in /var/log and nothing suspicios

It's really down to the kernel to support the chipset, not the distro. If you can find out the chipset and also which kernel drivers support it, you may be able to recompile your kernel with support. Or, on the other hand, if it turns out that the support for your chipset is bad/buggy perhaps you could add some kind of generic support and remove the bad kernel modules.

It sounds like you have some research to do to get this mobo running. If you have never compiled a kernel before there is a sticky at the top of this forum that shows how. I would recommend doing a 'make xconfig' as it's easier to find what you are looking for than 'make menuconfig'.

I would think that if the chipset is not supported it wouldn't work at all. But I guess it could be that the chipset is supported but the drivers are buggy.

I see that you have a P45 northbridge, and ICH10R southbridge. And a extra JMicron SATA controller. I know the ICH10R is new and not well supported, but this would only affect things connected to the southbridge like the HDD and DVD-ROM drive. I doubt any of these would cause a crash.

I guess maybe post the output of '/sbin/lspci -vv', it might help.

Another thing to make sure is that nothing is overheating, if this system is older, then clean off the dust inside.

One thing you could try is compile the latest kernel and see if things are better supported there.

I went to my supplier of hardware and return the mobo ...
they agreed to take it and give me in return any other mobo i want ...

So ... please help me chose another mobo that will work with no trouble at all, link of post: http://www.linuxquestions.org/questi...d-ddr3-688517/
